Filed: 1980-08-07
Abstract: PURPOSE:To adjust internal pressure by a method wherein adsorbents are arranged with a main body in a container and the adsorbents are adsorbed to insulating gas and the adsorbed gas is discharged to a cooling liquid when the adsorbents contact with the insulating gas. CONSTITUTION:The temperature of a cooling liquid 3 is low and the most of the internal pressure is insulating gas and liquid level is high at the time of starting operation. Adsorbents 81 in a tank 8 are immersed in a liquid 3 adsorbing no gas. Gasification of the cooling liquid promotes with temperature rise to drop liquid level and to expose the adsorbents 81 and the insulating gas is flowed into the tank 8 from a pipe 10 for adsorption and an increase in gas pressure is checked. In this case, liquid freon is replaced with gas SF6 in the adsorbents 81. With temperature decreased, the adsorbents sink below the liquid level of the cooling liquid to discharge the gas. In this composition, the internal pressure in the container can automatically be adjusted by a simple device.

IPC: B02C19/06
Filed: 1992-04-30
Abstract: PURPOSE:To obtain a magnet powder having a high magnetic characteristic by controlling the content of particles of 1mum or below in size to a specified value or less in volume ratio. CONSTITUTION:A magnetic powder containing at least one of the rare earth elements and Y, at least one of the transition metal elements, and at least one of N, O, H, B and C, and further having a hexagonal or rhombic Th2Zn17 type structure. The R-Fe-N magnet powder has its magnetic domain singularized but it has a wide particle size distribution. This, especially the presence of fine particles of 1mum or below, prevents a magnet material from developing its maximum characteristics. By narrowing and unifying the particle size distribution the characteristics of a magnet will be improved; it is required to reduce the content of fine particles of 1mum or below to 10% or less in volume. 5% or less is preferable and 1% or less is the best. A thus obtained magnet powder is highly magnetized and has a high rectangularity ratio, useful as a powder for permanent magnets.
